To all whom it may Be it known that which the following is aspecification.

The present invention relates to new and useful improvements in wirestretchers.

An object of the invention is the provision of a wire stretcher whichcan be applied to a post of usual construction and can be so operated asto tighten the wirewhereby it can be stretched and tacked to the post insaid tightened or stretched position. i

Another object of the invention is the pro which maybe used as a wiretightener in the middle of a fence and left there in position so thewire may be stretched at any future time. For this reason the crank isdetachable making it possible to have two or morestretchers and only onecrank. 1

Another object of the invention is the provision of a pivotedmeans forengaging the post and locking the wire against loosening after it hasbeen stretched to the desired tension.

A further obj prove and simplify ect of the invention is to im- Fig. 4Cis a detail perspective view of thebar;

Fig. operating crank, and

Fig. 6 is a detail sectional view showing the locking arm.

Referring to the accompanying drawings wire stretchers, 'render-' 111gthem comparatlvely simple and 1neXpen- 5 is a detail perspective view ofthe by corresponding characters of reference throughout the severalviews, the numeral 7 designates a post to which the wire 8 is to befastened after it is stretched to the desired tension.

Ihe wire stretcher is shown in general at 9 and consists of a body orbar 10 having a slot 11 formed therein with an offset end opening 12through which the wire to be stretched is insertedinto the slot 11." Oneend of the bar 10 is notched as at 13 and in: i this notch is pivoted alocking arm 14:

adapted when in the dotted line positions shown in Figs. 2 and 6 topermit the rotation of the bar 10 by a suitable operating crank 15 andwhen in the full line position shown in these two figures, to lockthebar 10 against rotation. 1

A suitable shoulder 16 is provided atthe lower endof the notch 13 whichlimits the v outward. movement of the arm lfpreventmg it from becomlngengaged with the post .7 during the operation of the device;

In use the bar 10 is placed with one side against the post and the wirestretched across the latter and is brought into engagement with thenotch 11.. As the bar 10 is rotated the wire 8 will be wound upon thebar 10 until it reaches a sufficient tension after whichit istacked tothe post 7 and the wire then disengaged from the notch or slot 11permitting the device tobe removed and positioned adjacent the nextdesired post. I

From the foregoing description takenin connection with the accomp anyingdrawings it will bemanifest that a wire stretcher is provided which willfulfil all of the necessary requirements of such a device.

Having thus fully described the invention what I claim to be new anddesire to protect by Letters Patent'is:

1. In a wire stretcher, the combination of a rotatable bar, having aslot therein for receiving a strand of wire, a detachable crank forrotating said bar, and an arm pivoted to I the end of said bar forlocking the same against rotation. v

2. The combinationin a wire stretcher, of a rotatable bar adapted toengage one side of a fastened post, a slot formed in said bar forreceiving a strand of wire, a notch openswung into the path of the 7 I Hgagement therewith and locking the bar.

bar and permitting the insertion of the strand of wire thereinto,afldetaehahle crank adapted to engagewone end of thehar for rotating thelatter apivoted arm attached to one end of the bar and adapted to bepost for Yene and means for limiting the In testimony whereof I aflix mysignature in the presen Witnesses ce of two Witnesses.
